How do I change the shutdown order so that shutdown does not hang, due to the diskless nature of a root file system on AoE?

I just got my diskless clients working with '/' being mounted over AoE during the boot process.. but now I'm trying to fix the init system's shutdown order.. where the net interface is evidently being shutdown prior to all other services being shutdown which causes the shutdown to hang.

I'm studying the situation atm, but a little help from anyone would certainly be appreciated.
